Immobilizer System Check
  1. Connect the HDS to the data link connector.
  1. Turn the ignition switch to ON (II).
  1. Monitor the System Check in the Immobilizer Info with the HDS.
    System Check No.
    System Check
    Possible Cause
    A-1
    The key is not registered
    • This key is not registered in the immobilizer-keyless control unit. Try to register keys using the HDS.
    • No communication between the antenna and the immobilizer key because of interference from metal such as key chains/key rings/other keys.
    • Low battery voltage.
    A-2
    Communication error between the key and immobilizer unit
    • Intermittent interruption between transponder and immobilizer-keyless control unit.
    • The immobilizer key type is incorrect non-Honda key.
    • Key failure (transponder failure)
    • No communication between the antenna and the immobilizer key because of interference from metal such as key chains/key rings/other keys.
    • Low battery voltage.
    A-3
    No communication between the key and immobilizer unit
    • The ignition switch was turned to ON (II) with a non-immobilizer key.
    • The immobilizer key type is incorrect non-Honda key.
    • Key failure (transponder failure)
    • No communication between the antenna and the immobilizer key because of interference from metal such as key chains/key rings/other keys.
    • Low battery voltage.
    • Immobilizer-keyless control unit failure
    B-1
    The ECM/PCM is not registered
    • The ECM/PCM was not registered. Try to register the ECM/PCM using the HDS.
    • No communication between the ECM/PCM and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the immobilizer-keyless control unit and the ECM/PCM because of interference.
    • Open in the IG1 line
    B-2
    Error of communication format in ECM/PCM
    • The ECM/PCM was not registered. Try to register the ECM/PCM using the HDS.
    • No communication between the ECM/PCM and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the immobilizer-keyless control unit and the ECM/PCM because of interference.
    C-1
    No registration of Imoes Unit
    • Imoes unit was not registered.
    • No communication between the imoes unit and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the imoes unit and the immobilizer-keyless control unit because of interference.
    C-2
    Error of communication format in Imoes Unit
    • Imoes unit was not registered.
    • No communication between the imoes unit and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the imoes unit and the immobilizer-keyless control unit because of interference.
    D-1
    S-net line short
    • Harness short from the ECM/PCM to the immobilizer-keyless control unit. (IMOCD (S-net) line short)
    • No communication between the ECM/PCM and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the immobilizer-keyless unit and the ECM/PCM because of interference.
    • Immobilizer-keyless control unit failure
    • ECM/PCM failure
    D-2
    No communication between Imoes Unit and Immobilizer Unit
    • Blown fuse
    • Harness open from the imoes unit to the immobilizer-keyless control unit. (IMOCD (S-net) line open)
    • No communication between the imoes unit and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the imoes unit and the immobilizer-keyless control unit because of interference.
    • Immobilizer-keyless control unit failure
    • Imoes unit failure
    D-3
    No communication between ECM/PCM and Immobilizer Unit
    • Blown fuse
    • Harness open from the ECM/PCM to the immobilizer-keyless control unit.
    • No communication between the ECM/PCM and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the immobilizer-keyless control unit and the ECM/PCM because of interference.
    • Immobilizer-keyless control unit failure
    • ECM/PCM failure
    E-1
    Initial registration of Immobilizer Unit is not completed
    The immobilizer-keyless control unit is not registered. Try to register the immobilizer-keyless control unit using the HDS.
